The Forms Tear-Off feature allows a printed continuous forms page to
be torn off without wasting paper or adjusting the printer.
When printing stops, Forms Tear-Off automatically moves the paper to
align the perforation with the tear bar (located under the access
cover), after a time interval which you select through the menu.
Paper remains in the tear-off position until the printer receives more
data. Then, the paper moves back down for printing.
This feature has to be enabled.
Paper Park
Your printer’s Paper Park feature allows you to print a single sheet
(cut-sheet) page without removing continuous feed paper from the
printer.
For more information, see “Paper Park” in “Using your Printer”.

INTERFACES - GENERAL
Your printer is equipped with a selection of data interfaces:
Under no circumstances attempt to use both parallel and USB ports
simultaneously.
Windows NT 4.0 does not support USB. Administrator
privileges are necessary for Windows 2000 and Windows XP
installations.
– For direct connection to a PC. This port requires a
– For connection to a PC running Windows 98 or above
to Windows 98) or Macintosh.
PRINTER DRIVERS > 10
Page 11
This port requires a cable conforming to USB version 1.1 or
above. A genuine cable displays the Trident symbol on both
connectors.
Using an inferior cable can cause printing problems and
special cables are needed for longer runs than five metres
.
The operation of a printer is not assured if a USB compatible
device is connected concurrently with other USB compatible
machines.
When connecting multiple printers of the same type, they
appear as *****, ***** (2), ***** (3), etc. These numbers
depend on the order of connecting or turning on each printer.
CONNECTING THE USB CABLE
Due to the number of possible variants of operating systems it is not
possible to describe every combination.
Terminology may vary between Windows operating systems and some
knowledge is assumed. If you are unsure how to proceed, you should
consult your computer documentation or system manager for details.
This example uses Windows 2000 Professional.

4.
Ensure the printer and computer are easily accessible and turn
both units off. This is not strictly necessary but may prevent
any problems being caused by the accidental dislodging of
power or other cables.
Plug the Series A Male connector (a) into
the computer’s USB port or into a
suitable USB hub.
b
Plug the Series B male connector (b) into
the printer’s USB port.

Switch on both the computer and printer.
PRINTER DRIVERS > 11

The printer will be identified
immediately by the New Hardware
Wizard and install itself in the Printer
folder. An additional item, USB Printing
Support will also appear in the Device
Manager each time the printer is
switched ON and connected.
6.
7.
8.
Check that the default paper size has
been correctly set by looking at the
settings in the Settings > Printers folder.
Under the printer's Properties > General
tab, the current paper selection is
shown. The printer picks up its initial
setting from the Locale settings on the
host computer. The paper size can be
altered by using the drop down arrow
and selecting an alternative size.
If the printer had formerly been used as a parallel or serial
device and there is no output from the printer once a USB
cable has been connected, check to see that the correct port
has been selected. This information can also be found in the
Properties folder but under the Ports tab. Amend as necessary.
If there are printing problems, check to see whether there is a
USB connection active in the Control Panel. If there is no USB
connection shown, you must install the hub.
9.
Alternatively, there may be a problem if the printer is
connected via a USB hub. Disconnect the printer cable from
the hub and connect it directly to the computer.

FORMS TEAR-OFF FEATURE
This feature is normally turned off. To use Forms Tear-Off, you must
enter the menu and change the setting to the desired time interval
(see “Changing the Forms Tear-Off Settings”).
The Forms Tear-Off feature allows a printed continuous forms page to
be torn off without wasting paper or adjusting the printer. It can be
used for rear feed continuous forms, bottom feed continuous forms
(with the optional push tractor installed), or for top feed roll paper
(with optional roll paper stand installed).
When the printer is turned on, the paper feeds to the tear-off position.
USING YOUR PRINTER > 18
Page 19
When data is received, the paper automatically moves down to the
print position (TOF) and printing begins.
NOTE
You can also move the paper down to the print position manually by
pressing
TEAR
.
When printing stops, Forms Tear-Off automatically moves the paper to
align the perforation with the tear bar (located under the access
cover), after the time interval which you selected through the menu.
Paper remains in the tear-off position until the printer receives more
data. Then, the paper moves back down for printing.
NOTE
>The status of the Forms Tear-Off menu setting affects how you set
the Top of Form: see “Top of Form (TOF) and Forms Tear-Off” earlier
in this chapter.
>Do not use Forms Tear-Off with labels or multipart forms!
>Forms Tear-Off cannot be used when the optional pull tractor is
engaged.
POTENTIAL ISSUES WITH SOFTWARE PACKAGES
If Forms Tear-Off is set to ON and the software package you are using
“pauses” for a long enough interval while sending data to the printer,
Forms Tear-Off may be activated. No data is lost, but this causes
uneven print registration due to the paper movement.
If this occurs, use the menu to turn off this feature, then use the TEAR
key to move the paper up to the tear position manually (see
“Changing the Forms Tear-off Settings”).

TROUBLESHOOTING
GENERAL INFORMATION
Here are some general things to check before proceeding with
detailed troubleshooting.
lIs the printer plugged in and turned ON?
lAre the connections (power and interface) secure?
lIs the product being operated under the proper ambient
conditions?
lDoes the paper being used meet the specifications for this
product?
lIs the paper properly installed?
lIs the ribbon properly installed?
lIs an Oki ribbon being used?
lIs the printhead gap correctly set?
lAre the correct printer drivers being used for the printer?
NOTE
>Settings in your software application will normally override any
settings in your printer driver.
>Printer driver settings normally override settings from the printer
menu or printer front panel.

Solution
The Operator Panel Function in the printer menu can be used to
disable these buttons (Limited Function). If the printer is part of a
